Referring to fig. 1, 2 and 4, the launching device of the present embodiment includes a frame 100, a damper 200, a rope winding roller 300, and the like. The damper 200 is fixedly coupled to the frame 100, and the rope winding roller 300 is coupled to the coupling shaft 210 of the damper 200. The rope winding roller 300 is provided with a lug 310 on the roller shaft, and one end of the suspension rope 400 forms a loop 410 and is sleeved on the lug 310. The hanging rope 400 is wound around the rope winding roller 300, and the free end thereof is fixed to the object 900 to be thrown. For example, a snap hook may be provided at a degree of freedom of the hanging string 400, and the object 900 to be placed may be fixed by the snap hook to facilitate the detachment of the object 900 to be placed. As the rope winding roller 300 rotates, the hanging rope 400 is continuously paid out until the loop 410 at the end thereof is disengaged from the lug 310, and the object 900 to be thrown falls in the throwing position together with the hanging rope 400. When the string 400 is wound around the winding roller 300, the loop at the end of the string 400 is covered so as not to cause the loop 410 to come off the lug 310 even when the string 400 is not completely unwound.

In this embodiment, the damping amount can be adjusted by the damper 200, so that the rotation resistance of the rope winding roller 300 is increased, the rope winding roller 300 can rotate slowly, the suspension rope 400 is discharged slowly, the object 900 to be placed descends slowly, the speed of the object 900 to be placed on the ground is reduced, the impact degree between the object 900 and the ground is reduced, and the possibility of damage is reduced.

In some embodiments, the length of the suspension line 400 can be selected to match the drop height such that after the suspension line 400 is fully deployed, the height of the object 900 from the ground is as small as possible, or even close to zero, to further reduce the impact of the object 900 falling on the ground. When the length of the suspension rope 400 is equal to the throwing height, the object 900 to be thrown will be slowly paid out and placed on the ground.

Referring to fig. 1 to 3, in some embodiments, a holding member 500 and a driving member 600 are further provided, and the driving member 600 is connected to the frame 100, and the driving member 600 can drive the holding member 500 to move, for example, move or rotate, so as to hold it against the rope winding roller 300, so as to restrain the rope winding roller 300 from rotating and perform a braking action. During the throwing process, if severe weather occurs, for example, when wind force is large, the falling of the object 900 to be thrown may be unstable. At this time, the rotation of the rope winding roller 300 can be stopped by the abutting piece 500 abutting against the rope winding roller 300, the object 900 to be thrown in the air is stopped, after the weather is improved, the abutting piece 500 is separated from the rope winding roller 300, and the rope winding roller 300 can continue to rotate.

In some embodiments, the holding member 500 can be driven by the driving member 600 to hold the end of the rope winding roller 300 for braking. Compared with the rope winding roller which is abutted against other positions, the end part of the rope winding roller 300 is smoother, the contact area is larger, the rope winding roller is more stable in abutting, and the rope winding roller is not easy to slip.

In some embodiments, the holding member 500 is rotatably connected to the frame 100, and the driving member 600 drives the holding member 500 to swing with respect to the frame 100 to hold or separate from the rope winding roller 300. In this embodiment, in order to reduce the weight, the driving member 600 is a steering engine, so that the swinging of the holding member 500 can be matched with the motion mode (rotation) of the steering engine.

In some embodiments, the connecting member 700 is rotatably connected to the supporting member 500 at a position on one side of the connecting position of the supporting member 500 and the frame 100, and the position on the supporting member 500 capable of supporting the rope winding roller 300 is on the other side of the connecting position of the supporting member 500 and the frame 100. The driving member 600 can drive the connecting member 700 to move, and when the connecting member 700 moves, the supporting member 500 is driven to rotate relative to the frame 100, so as to approach or move away from the rope winding roller 300. Specifically, the driving member 600 can drive the connecting member 700 to move or rotate, so as to drive the abutting member 500 rotatably connected therewith to rotate.

In some embodiments, the driving member 600 is connected to the rotating member 800, and the rotating member 800 is driven to rotate by the driving member 600. The rotating member 800 is provided with a sliding groove 810, one end of the connecting member 700 is rotatably connected with the holding member 500, and the other end thereof extends into the sliding groove 810. The driving member 600 drives the rotating member 800 to rotate along the first direction until the groove wall of the sliding groove 810 abuts against the connecting member 700, and then, when the rotating member 800 continues to rotate, the connecting member 700 moves under the pulling of the groove wall of the sliding groove 810. When the connecting member 700 moves, the supporting member 500 is driven to swing relative to the frame 100, and gradually approaches and supports the rope winding roller 300. The sliding groove 810 is matched with the connecting piece 700, and is suitable for the condition that the rotating stroke of the driving piece 600 is overlarge. For example, the rotation stroke of the steering engine is 90 degrees, and only the connecting member 700 needs to be driven to rotate by 20 degrees, and due to the existence of the sliding groove 810, the steering engine can drive the rotating member 800 to idle for a period of time, and the connecting member 700 can not be pulled to move until the groove wall of the sliding groove 810 abuts against the connecting member 700. Thus, the drive member is more selective without the need to specially design a specific matching drive member.

In some embodiments, the supporting member 500 includes a supporting member main body 510 and a supporting member swing arm 520, which are rotatably connected by a first rotating shaft 531, and the supporting member main body 510 is circular ring-shaped and is used for supporting against the rope winding roller 300. The holding member swing arm 520 is rotatably connected to the connecting member 700 via a second rotating shaft 532, and the holding member swing arm 520 is rotatably connected to the frame 100 via a third rotating shaft 533. The connecting member 700 drives the supporting member swing arm 520 to swing relative to the frame 100, and further drives the supporting member main body 510 to move, so as to realize supporting. If only one integrally connected component is provided as the abutting member 500, when the rotating component abuts against the rope winding roller 300, the abutting area is smaller (compare on the premise that the area of the end of the abutting member 500 for abutting is the same). When the supporting member swing arm 520 swings to drive the supporting member main body 510 to move, the whole end surface of the supporting member main body 510 moves along the axial direction of the rope winding roller 300 and supports against the rope winding roller 300, so that the supporting area is larger, and the supporting process is more stable.

In some embodiments, the distance between the axis of the first rotating shaft 531 and the axis of the third rotating shaft 533 is greater than the distance between the axis of the second rotating shaft 532 and the axis of the third rotating shaft 533. Thus, the supporting member 500 is equivalent to a laborious lever, when the joint of the supporting member swing arm 520 and the second rotating shaft 532 swings by a small angle, the joint of the supporting member swing arm 520 and the first rotating shaft 531 can swing greatly, the supporting member main body 510 can support the rope winding roller 300 more quickly, the reaction delay caused by the idling of the driving member 600 can be partially offset, and the braking can be realized as soon as possible.

In some embodiments, the retainer swing arm 520 includes a first arm 521 and a second arm 522, both of which are arc-shaped and define a receiving cavity to receive the retainer body 510. The first arm 521 and the second arm 522 are respectively connected with two sides of the holding part main body 510 in a rotating manner, and the two sides are connected to each other, so that the stability of the movement process of the holding part main body 510 can be improved.

Referring to fig. 4, in some embodiments, a drone includes the launch device of the embodiments described above. This put in device sets up on unmanned aerial vehicle's cloud platform 1000.

Referring to all the drawings, when the dispensing device in some embodiments is used for dispensing, the adjusting knob 220 on the damper 200 is rotated to adjust the rotation resistance of the rope winding roller 300, so that the rope winding roller 300 rotates slowly at a proper speed, and the hanging rope 400 is slowly released to descend with the object 900 to be dispensed. If unstable factors such as strong wind occur during the descending process, the driving member 600 drives the rotating member 800 to rotate along the first direction until the sliding groove 810 abuts against the connecting member 700 and drives the connecting member to rotate. The connecting member 700 drives the holding member swing arm 520 to swing in the first direction, so that the holding member main body 510 rotatably connected to the holding member swing arm 520 gradually approaches the end of the rope winding roller 300 to form holding, and the rope winding roller 300 is braked by friction. After the bad weather is over, the driving member 600 rotates reversely, the above components move reversely, the holding member body 510 gradually moves away from the end of the rope winding roller 300, and the rope winding roller 300 continues to rotate.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
